Ghana midfielder Joseph Alfred Duncan has made full recovery at Cagliari.
Duncan joined the Islanders on a loan deal with the option to purchase at the end of the season.
The 27-year-old had a superb start to life in Sardinia until he picked an injury in the 1-0 defeat at Genoa on matchday 19.
He consequently missed the 1-1 stalemate with former club Sassuolo and also the 1-0 loss at home to Atalanta over the weekend.
Duncan has however recovered from the setback, having joined his teammates in training ahead of their next Serie A-game.
Cagliari will host Torino at the Sardegna Arena on Friday.
